Just my view but all LED headlamps are very bright. They generally don't dazzle people on dipped beam because of the exceptionally sharp cutoff of light above a certain level/distance. This cutoff line is very apparent on the rear valance of any car you may be following, as noticed on both my Roadster and our three year old Mini.
Obviously they require careful adjustment and use of dipped beam. They also present a worst case scenario when your car crests a steep hill and an oncoming vehicle is looking up into them. I would imagine a Mog scrores better here given its low headlamp location though. It's firm front suspension is also an advantage limiting the bouncing of light onto oncoming.
Regarding Heinz query on cooling, undoubtedly the open back bowls would seem to offer better cooling but not a justifiable option for my car. I convinced myself given headlamp location and loose fit of headlamp rim to lens, there will be plenty of air flowing around the standard bowl. After a one hour journey in the dark I could detect no heat at all eminating from them.
BTW on the journey mentioned returning from visiting Cain, and on the A11 a new Aston shot past me. The drivers enthusiastic style meant brake lights were constantly on and off as he attempted to make brisk progress in the outer lane. As I followed at a safe distance, this wouldn't have been a worry but for the unmistakable high level LED brake light repeater stretching the full width of rear screen. Could not believe this huge band of exceptionally bright solid red light could be legal
